13 Claims. (Cl. 20-92) Thisinventionrelates to fastening devices andfasteners and to means for. fastening together` adjacent structures andmore particularly to devices for locking or fastening together adjacentpanels ofportable houses,- large packing cases, trunks or the like,thoughit is notedfthat in'many ofthe, claims the invention is notlimited to securing panels. I

Objectsv of the invention are toprovid`e an improved very;` strongfastening device of this k'indwhich may-be quickly operated 'to reliablysecuretwo structures together, and which will unyieldably orautomatically yieldably draw; the-.structures together and remaininlocked or un locked; position and: which will' accommodateinaccuracies and misalinementiwhen bringing' the structures together.

Other objects ofthe invention are to provide-an improvedz'devicek ofthis lkindadaptableforpanels or the like in the? same'plane or at arightfang-leto each other and to. provide.` means for lockingV thefastener inlocked position'. Additional: objects of the invention arevto effect simplicity and efficiencyY in such fasteners and toprovide anextremely simple device of this kind which isconvenient, speedy, durableandreliable in operation, and economical tomanufacture andinstall. v

Stillother objects of the invention will appear as thedescriptionproceeds;and'while hereindetails of the` invention aredescribed'in thespecication and some of the claims, the inventionasdescribed in the` broader claims is not limited to these, and manyandvarious changes may. be made withoutY departing from thescopeofthe'invention as claimed in the broader claims;

An eccentric pin 52 fast in said bolt and projectingfrom said flat end face is provided with a rivetj head 53 .forming ashoulder in the plane of the exposed face of the slide member. A shortatrlink 55 (Figs. 2 and 6) Vin said opening of the slideimember ispivoted on the eccentric pin 52 'and has an approximately completecircular end 56 (Fig. 6) and a narrow neck 57 connecting the circularendwith the pivot end. The opening 44 of the slide member has a partlyclosed circular part 58 nearest the pivot carrying member and openingtoward the pivot pin and pivotally receiving said circular endV 56, saidopening being formed to allow the eccentric pin to move-with a toggleaction from dead centerV to Ydead center and slightly beyond, and tostop the pin when it moves slightly vbeyond the dead center, Theeccentric pin v52 is such a distance from the axis of the bolt 46 andthe keeper lip 42 that when the eccentric pin is nearest said lip, saidhook 38 may clear the keeper lip, and when said eccentric pin is at thedead center most remote from the keeper lip, said hook tightly engagesthe lip to force the panels together. A

Alined bores 79 (Figs. 2 and 5) at diametrically opposite sides of thebolt head 47 pivotally receive inturned pivot journals 83 (Fig. 3) of abutterfly 82, whereby the buttery may be disposed in raised position, asin Fig. 3, diametrically of the bolt thus adapting the bolt to be turnedby hand in locking position, or turned substan- .tially against saidside ears and edge shoulders 19 of.

Said pivot journals 83are square in cross section providing side faces 85, 86 parallel andperpendicular to the plane of the buttery. The inner face of the bolthead is provided near the periphery with an annular groove 87 (Fig. 5)receiving a `spring-split ring 88 swaged or otherwise anchored as at 89remote from said journals, said ring pressing against said side faces 86or 85 to yieldably hold the butterfly in said raised position or inlocking position adjacent to the edge shouldei 19 of side ears 17. Theslide member is axially provided with a U-shaped slot or cut 90 havingits yokepart 91 adjacent to said opening 44 of the slide memberand-forming a tongue 92 provided with an indentation 93 received in arecess 94 (Fig. 5) in the at end face 49 of the bolt near its periphery,when the bolt is inV locking position, to yieldably stop the bolt inlocking position when the butterfly is raised, or if it or the edgeshoulders 19 are-not provided.
